CORNER-JOINT FOR PACKING-BOXES.

SPECIFICATION forming part of Letters Patent No. 411,924, dated October 1, 1889.

Application filed February 16, 1889. Serial No. 300,135. (No model.)

To col; whom it may concern.-

Be it known that I, ALBERT T. LINDERMAN, a citizen of the United States, residing at Whitehall, in the county of Muskegon and State of Michigan, have invented a new and useful Improvement in Corner-Joints for Packing-Boxes, of which the following is a specification.

My invention relates to improvements in corner-joints for packing-boxes; and its object is to provide a tight, cheap, strong, and neat box which can be easily put together by hand or machine. I attain this object by forming the corner-joints in the manner shown in the accompanying drawings, in which- Figure l is a perspective of the sides and ends of a box joined after the manner of my invention. Fig. 2 is a partial horizontal section, and Fig. 3 shows sectional views of the abutting portions of one of the sides and ends detached.

Like letters of reference indicate like parts throughout the several figures.

Insaid drawings, A A represent the ends and B B the sides of the box. The ends of the end pieces are formed as more particularly illustrated at Fig. 3, this formation consisting of a groove like a dovetail upon the outer side, as at c, and at the inner side of the groove the stuit is all cut away except a low square tongue, as shown at (Z. The side pieces are beveled at their ends, as at e, and

provided with a groove f, adapted to receive the tongue d of the end. The edges of the stuff may be thus fashioned by passing them across a series of saws, and the parts are then assembled together by sliding one into the other in the usual manner of joining dovetailed stuff. The joint, it will be noticed, resists separation in every direction except the longitudinal one, and it will also be noticed that a complete dovetail is formed if the two ends be considered together or unitedly, one-half of the dovetail being formed in each. When the top and bottom are nailed, the ends and sides are securely held against any movement in the only direction in which the peculiar joint allows any freedom.

Among the advantages of this construction of box are great strength, the extent to which the sides lap upon the ends thereby affording abundant room for nailing, if that should be desirable, neatness of appearance, and ease and speed of manufacture.

I claim- The joint for the corners of packing-boxes, wherein one part is provided with the be velgroove 0 and tongue (1, and the other part is provided with the bevel e and groove f, substantially as set forth.
